Beta LaserMike recognises that the
accurate measurement of lay length in
twisted pairs is a critical factor in Category
cable performance. The latest LayScan
system enables telecommunication cable
manufacturers to dramatically improve
product performance, quality and
consistency.
Until now, the ability to accurately
measure the lay length of twisted-pairs at
the cabler and twinner stations has been
a manual and time-consuming process.
This manual process results in inaccurate
and unreliable measurements.
Factors such as the pair lay length and
the variations of the lay in twisted-pair
Category cables, such as Cat 5e/6/6a/7a
products, directly affects crosstalk
performance. Cables that do not meet
the far- and near-end crosstalk and
product quality specifications wind up
being scrapped, significantly costing
manufacturers in rework, materials and
overall productivity losses.
With the focus on producing higher
quality cable in less time and at a lower
cost, the LayScan measurement system
from Beta LaserMike offers manufacturers
an accurate and consistent method to
measure the lay length of twisted pairs
used in telecommunication cables.
The LayScan system enables
manufacturers to simultaneously
measure four pairs at the cabler to
confirm the accuracy of twisted-pair cable
construction during production. This
non-contact system uses four individual
pair lay sensors and Beta LaserMike’s
LaserSpeed length and speed gauge
to perform the high-speed lay length
measurements.
A data acquisition and control system
effectively collects and processes each lay
length in the cable and allows the full use
of the customer’s off-line analysis tools
such as trend charts, statistical analysis, or
FFT analysis to readily observe, measure,
and report systematic lay variations
within each lay.
Data can be easily stored on a local
PC. The LayScan system performs
measurements to within 0.025mm
(0.001") overall accuracy on the same
twisted pair. It can measure lay lengths up
to 25.4mm (1") at throughput speeds up
to 152.4m/min (500ft/min).

Sandvik’s new wire, Safeni 52, has precisely
the right material characteristics and a
new level of feedability that contributes to
higher throughput with less downtime.
Safeni 52 is a soft magnetic iron-nickel
alloy with high magnetic permeability,
low coercive force, and a low content
of non-metallic inclusions. Its thermal
expansion is compatible with glass used in
reed switches.
Using Safeni 52 wire, reed switch
manufacturers can rely on consistently
high surface quality, which contributes
to the wire’s feedability. It runs through
equipment cleanly, contributing to higher
production throughput with increased
uptime as well as high end-product quality
and reliability.
Packaging is designed to reduce
tangled pails and the wire exhibits
remarkable straightness with little cast
or helix. Together these benefits give
manufacturers switching to Safeni 52
wire the potential to take on more
business without capital investment.
Reed switches incorporating Safeni 52
have a very consistent level of reliability
and long operational lifetimes, which will
contribute to a high yield with very good
quality.
Pure Sandvik Safeni 52 wire is produced
entirely in-house by Sandvik. The company
controls the entire process, from alloy
melting and wire drawing through to
packaging, and, thus, the quality and
reliability of the product. Before leaving
the plant, the wire is rigorously tested.
In addition, Sandvik’s close proximity to
customers worldwide ensures a robust and
reliable material supply chain. Safeni 52
wire is available in a wide variety of forms
and diameters.
